Thanks for the report! Unfortunately at the moment I can't find out the cause of this unstable behavior. My guess is that there is not enough CPU performance to calculate the physics simulation of the liquids (such feature is present in every mini-game and requires quite a powerful mobile CPU). At least that would explain why the game works normally during regular gameplay and freeing only during mini-games. The game will probably run better when an updated demo with appear with some optimizations requested by mobile users, but the recommendation to have powerful CPU in system requirements will remain anyway, I will keep fluid physics simulation in any case.
Also, I have no information how the game works on Kirin and Mediatek platforms/chipsets, so far all tests and reports from players were related to Snapdragon and Exynos chipsets. Generally, the game works well on such phones after 2021 release (usually mid-end and high-end models).
